We may observe in these verses, 1. What David experienced of an affection to the law of God: "I seek thy precepts, Psa 119:45. I desire to know and do my duty, and consult thy word accordingly; I do all I can to understand what the will of the Lord is and to discover the intimations of his mind. I seek thy precepts, for I have loved them, Psa 119:47, Psa 119:48. I not only give consent to them as good, but take complacency in them as good for me." All that love God love his government and therefore love all his commandments. 2. What he expected from this. Five things he promises himself here in the strength of God's grace: - (1.) That he should be free and easy in his duty: "I will walk at liberty, freed from that which is evil, not hampered with the fetters of my own corruptions, and free to that which is good, doing it not by constraint, but willingly." The service of sin is perfect slavery; the service of God is perfect liberty. Licentiousness is bondage to the greatest of tyrants; conscientiousness is freedom to the meanest of prisoners, Joh 8:32, Joh 8:36; Luk 1:74, Luk 1:75. (2.) That he should be bold and courageous in his duty: I will speak of thy testimonies also before kings. Before David came to the crown kings were sometimes his judges, as Saul, and Achish; but, if he were called before them to give a reason of the hope that was in him, he would speak of God's testimonies, and profess to build his hope upon them and make them his council, his guards, his crown, his all. We must never be afraid to own our religion, though it should expose us to the wrath of kings, but speak of it as that which we will live and die by, like the three children before Nebuchadnezzar, Dan 3:16; Act 4:20. After David came to the crown kings were sometimes his companions; they visited him and he returned their visits; but he did not, in complaisance to them, talk of every thing but religion, for fear of affronting them and making his conversation uneasy to them. No; God's testimonies shall be the principal subject of his discourse with the kings, not only to show that he was not ashamed of his religion, but to instruct them in it and bring them over to it. It is good for kings to hear of God's testimonies, and it will adorn the conversation of princes themselves to speak of them. (3.) That he should be cheerful and pleasant in his duty (Psa 119:47): "I will delight myself in thy commandments, in conversing with them, in conforming to them. I will never be so well pleased with myself as when I do that which is pleasing to God." The more delight we take in the service of God the nearer we come to the perfection we aim at. (4.) That he should be diligent and vigorous in his duty: I will lift up my hands to thy commandments, which denotes not only a vehement desire towards them (Psa 143:6) - "I will lay hold of them as one afraid of missing them, or letting them go;" but a close application of mind to the observance of them - "I will lay my hands to the command, not only to praise it, but practise it; nay, I will lift up my hands to it, that is, I will put forth all the strength I have to do it." The hands that hang down, through sloth and discouragement, shall be lifted up, Heb 12:12. (5.) That he should be thoughtful and considerate in his duty (Psa 119:48): "I will meditate in thy statutes, not only entertain myself with thinking of them as matters of speculation, but contrive how I may observe them in the best manner." By this it will appear that we truly love God's commandments, if we apply both our minds and our hands to them.

This is my comfort in my affliction,.... David had his afflictions, and so has every good man; none are without; it is the will and pleasure of God that so it should be; and many are their afflictions, inward and outward: the word of God is often their comfort under them, the written word, heard or read; and especially a word of promise, powerfully applied: this is putting underneath everlasting arms, and making their bed in sickness. This either respects what goes before, concerning the word of promise hoped in, or what follows:

for thy word hath quickened me; not only had been the means of quickening him when dead in am, as it often is the means of quickening dead sinners, being the savour of life unto life; but of reviving his drooping spirits, when in affliction and distress; and of quickening the graces of the Spirit of God in him, and him to the exercise of them, when they seemed ready to die; and to the fervent and diligent discharge of duty, when listless and backward to it.
